It would be very helpful to upload images/files for types as well. E.g for find types we could attach images showing examples of the find type for better understanding. These images could be displayed on the main entry of the type and it would also be good to show them on mouseover in the treeview when selecting the type

This would be a "frontend" issue and not a trivial one I would guess. But if we do it, we could implement it also for other entities like actors in forms.

It would need some kind of thumbnail generation which would be an own issue itself, otherwise it would take too long to load all the images in forms (thumbnail generation would also be a prerequisite for a slideshow)
